One of the best games of this generation, maybe ONE of the best games of all time, is Horizon Zero Dawn.
I bought the Complete Edition of Horizon Zero Dawn, it comes with the DLC, and all of the Pre-order bonus items, and much more, for only $50. That's less then a new AAA base game. lol.
It's well worth it in my opinion. And I'm having so much damn fun, it's insane. It's crazy how much original content they can pack into this game without the game becoming repetitive. Because Horizon is very far from repetitive. This is probably one of the very few games that I actually want to 100% the game, and still want to start a New Game+.
Honestly, I think Horizon Zero Dawn is just above Zelda Breath of the Wild on my Games of the Year list, with Zelda being number 2 on my list. Zelda was number 1, until I played Horizon for about 20 hours, then Horizon quickly took the number 1 spot on my list.
And this is coming from someone that has been a HUGE Zelda fan since the very beginning, with Zelda Ocarina of Time being my best Zelda game of all time. So trust me, it wasn't easy for me to drop Zelda BOTW to the number 2 spot on my Game of the Year list.
But if you do get Horizon, you MUST get the DLC too. Please. You will be glad you did. After you beat the main story, your going to want more and more of the story, so that's why I said you should also get the DLC if you do buy the game. You should get the complete edition, since it comes with everything.
